NC 250 S smoke bomb handling manual (1942) (ebook)

The NC 250 S is similar in size and construction to the German C 250 (Flam) bomb. The central tube contains a wooden block 20.5 inches long and 4.25 inches in diameter, cardboard disks, and a circular block of TNT 9 inches long and 4.25 inches in diameter. The bomb is fuzed with a E1AZ (26) which has a normal gaine and one picric ring pellet. The fuze operates directly on impact detonating the burster charge of TNT in the central tube. The main filling is scattered to give a large concentration of smoke. The filling is a corrosive mixture of chlorosulphonic acid (40%) and Sulphur Trioxide (60%) which, when in contact with the air, emits white smoke. The body is silver, the tail olive drab. The forward part of the nose, a 3/4 inch stripe part-way back on the nose, and a 1-inch stripe just aft of the suspension lug are painted white. "NC 250 S" is stencilled aft of the second band.
